This study aimed to compare the organoleptic and nutritional quality of four sheep meats produced in Morocco. This comparison was carried out by analyzing the proximate composition, amino acid profile, and mineral content of meat. The majority of the evaluated parameters were influenced by genetic and geographical factors ( p < 0.05 ). The longissimus lumborum muscle had higher a ∗ value in Timahdite and Ouled-Djellal breeds. The highest values of macroelement were recorded in samples of Beni-Guil meat sampled in the Tendrera region (BGT; 1067.3 mg/100 g), while the highest microelement content was registered in Timahdite meat (5.7 mg/100 g). Iron and zinc were the major identified trace elements, while phosphorus and potassium were the most abundant macroelements. The abundant amino acid was glutamic, while cysteine and methionine were least abundant. The higher essential amino acids index (IEAA) was recorded in the Timahdite sheep meat (162.20, 158.71, 161.02, and 159.65, respectively, for Timahdite, BGT, Ouled-Djellal breeds, and Beni-Guil meat sampled in Ain Beni Mathar region). From a nutritional point of view, the studied meats had a good protein and mineral quality, due to their richness in essential amino acids and microelements. The present study provided new insights on the organoleptic quality and the nutritional value of three Moroccan sheep meats reared in outdoor production system.

Several plants are utilized for medicinal and nutritional purposes. Irvingia gabonensis O’Rorke Baill leaf is used in herbal medicine for treatment of a number of ailments. This study was therefore carried out to investigate the proximate composition, antinutritional factors, mineral composition and amino acid profile of Irvingia gabonensis O’Rorke Baill leaf. The proximate and antinutritional factors analyses were done using standard procedures. The mineral analyses were done using flame photometry, titrimetic method, molybdo vanadate method and atomic absorption spectrophotometry and the amino acid profile was done with the aid of Applied Biosystems PTH amino acid analyzer. Results of proximate analyses were carbohydrates (75.15±1.29 %), protein (11.43±1.07 %), fat (1.99±0.74 %), fibre (4.89±0.61 %), ash (6.71±0.28 %), moisture (5.12±0.03 %) and caloric value (364.30±5.95 Kcal). Antinutrients (phytate, oxalate and cyanide) levels in the leaf were also very low. Results from mineral analyses obtained revealed that the leaf is also a very rich source of calcium, potassium, sodium, magnesium and so on. Compared with the World health organization (WHO) standards, results of the amino acid profile showed that the leaf is very rich in isoleucine, leucine, lysine, phenylalanine, threonine, valine and tyrosine which are nutritionally essential amino acids. Furthermore, extraction of the leaf using ethanol reduced the levels of these amino acids but not below the recommended WHO standard levels for most of the essential amino acids. Irvingia gabonensis O’Rorke Baill leaf is therefore a potential source of key nutrients.

Abstract The study assesses the proximate composition, amino acid profile and its content and chemical indices of the sun-dried Schilbe mystus, Bagrus bayad, Oreochromis niloticus, Clarias anguillaris and Petrocephalus bane bane from Tiga Dam Reservoir, Nigeria. The proximate composition varied significantly (p<0.05) in all five species of fish and these ranged as follows: Moisture (4.79 - 9.52 g/100 g), Crude Protein (42.20 - 57.71 g/100 g), Ash Content (0.90 - 12.51 g/100 g), Ether Extract (3.41 - 9.93 g/100 g), Crude Fibre (0.62 - 5.08 g/100 g), Nitrogen Free Extract (12.28 - 42.70 g/100 g) and Dry Matter (90.48 - 95.21 g/100 g). The amino acid also differed significantly (p<0.05). The nine essential amino acids found in the five species of fish were Lysine (4.21 - 6.34 g/100 g), Histidine (1.96 - 4.30 g/100 g), Arginine (5.80 - 8.21 g/100 g), Threonine (1.93 - 5.05 g/100 g), Valine (2.91 - 5.53 g/100 g), Methionine (1.74 - 3.80 g/100 g), Isoleucine (2.04 - 3.37 g/100 g), Leucine (3.64 - 7.18 g/100 g) and Phynylalanine (1.90 - 4.23 g/100 g). Whereas, the eight non-essential amino acids included: Serine (2.12 - 5.22 g/100 g), Glutamic acid (13.24 - 16.30 g/100 g), Proline (3.12 - 6.29 g/100 g), Glycine (4.20 - 9.08 g/100 g), Alanine (5.00 - 6.36 g/100 g), Cysteine (0.94 - 1.24 g/100 g), Tyrosine (2.33 - 3.33 g/100 g) and Aspartic acid (6.34 - 11.01 g/100 g). P. bane bane was first in terms of crude protein; S. mystus had the highest lipid and essential amino acid content. Also, C. anguillaris recorded the highest calorific value and best amino acid content. Thus, P. bane bane can serve as a source of animal protein to balance deficiencies in humans. Both S. mystus and C. anguillaris can be used as a nutrient base for high energy food and oil in the food industry.

The inability of humans to synthesize essential amino acids (EAA) necessitates the need to increase the levels of these nutrient molecules in certain foods in which they are deficient. Maize ogi is a typical food product for both infants and adults in Africa, but with poor EAA content. This study therefore sought to assess the possibility of increasing the EAA content in maize ogi by processing it with cheese whey instead of water. Maize ogi and whey-fortified ogi were prepared by the usual procedure of grain soaking, milling, and drying. Samples from both treatments were subjected to proximate composition and amino acid profile analyses using Waters 616/626 LC (HPLC) instrument. L-lysine, L-trytophan, and L-methionine contents in maize ogi remarkably increased from 0.52, 0.15, and 0.90 mg/100 gm sample, respectively, to 0.90, 240, and 1.320 mg/100 gm sample in whey-fortified ogi. There were also significant increases in other EAA contents of whey-fortified ogi relative to its counterpart (normal maize ogi). The sum increase in EAA contents (9,405 mg) correlates with the increase in protein (1 gm) per gram sample. This study demonstrates that cheese whey increases EAA content in maize ogi and suggests that whey-fortified maize ogi may be a preferred alternative to water processed maize ogi.

Study on the evaluation of the nutritional quality of poorly utilized plant products is of immense importance. This research work, therefore, evaluates the amino acid profile and mineral content of Balanites aegyptiaca kernel using standard analytical methods. The amino acid profile analysis revealed the presence of essential and the non-essential amino acids of which Total sulphur and Total aromatic amino acids content were 2.86 g/100 g protein and 7.21 g/100 g protein respectively. Analysis of the mineral content showed the presence of the following minerals in the order; Magnesium ˃ Sodium ˃ Calcium ˃ Potassium ˃ Iron ˃ Zinc ˃ Manganese ˃ Lead ˃ Copper ˃ Nickel ˃ Chromium ˃ Cadmium. The kernel could, therefore, be used as a good source of protein and minerals in supplementing other sources in order to reduce food insecurity and hence malnutrition from lack of protein diets.

Almond Oil

Almonds harvesting, along with precleaning, hulling, shelling, and sorting, generate recoverable co-products such as double, malformed, or damaged almonds. The common way that generates more benefit is the extraction of almond oil for food and cosmetic uses. The aim of this study is to compare composition and nutritional value of almond meals of the main varieties from eastern Morocco, Marcona (M), Fournat de Breznaud (FNB), FerragnesandFerraduel (FF) and Beldi a local ecotype (B), during three consecutive crop years (2016-2018). Significant differences were observed, which mainly concern the residual oil in almond cakes and especially their fibres, sugars, and proteins. Differences depend on the quality of the raw material and the effects of the crop year on the variety. Besides, from a nutritional point of view, analysed almond meals still contain significant amounts of residual oil and the major constituents of almond seeds (sugars, fibres, and proteins). The amino acid profile presents eight essential amino acids (Cysteine, Methionine, Isoleucine, Leucine, Phenylalanine, Tyrosine, and Lysine Valine) and the Protein Digestibility Corrected Amino Acid Score (PDCAAS) ranges between 24.78% for (M) and 62.17% for (FF). We conclude the analysed almond meals present interesting nutritional values as a specific ingredient for gluten-free culinary preparations and light foodstuffs.

Fish processing industries generate a large volume of discards. In order to fulfil with the principles of a sustainable circular economy, it is necessary to maintain aquaculture by-products in the food chain through the production of high-value biomolecules that can be used as novel ingredients. In this study, we try to give value to the gilthead sea bream by-products, evaluating the composition and the nutritional value of the muscle and six discards commonly obtained from the fish processing industry (fishbone, gills, guts, heads, liver, and skin), which represent ≈ 61% of the whole fish. Significant differences were detected among muscle and by-products for fatty acid and amino acid profile, as well as mineral content. The discards studied were rich in protein (10%–25%), showing skin and fishbone to have the highest contents. The amino acid profile reflected the high quality of its protein, with 41%–49% being essential amino acids—lysine, leucine, and arginine were the most abundant amino acids. Guts, liver, and skin were the fattiest by-products (25%–35%). High contents of polyunsaturated fatty acids (PUFAs) (31%–34%), n-3 fatty acids (12%–14%), and eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) (6%–8%) characterized these discards. The head displayed by far the highest ash content (9.14%), which was reflected in the mineral content, especially in calcium and phosphorous. These results revealed that gilthead sea bream by-products can be used as source of value-added products such as protein, oils, and mineral supplements.

The perturbation in plasma free amino acid metabolome has been observed previously in diabetes mellitus, and is associated with insulin resistance as well as the onset of cardiovascular disease in this population. In this study, we investigated, for the first time, changes in the amino acid profile in a group of people with and without type 2 diabetes (T2D) with normal BMI, from Jordan, who were only managed on metformin. Twenty one amino acids were evaluated in plasma samples from 124 people with T2D and 67 healthy controls, matched for age, gender and BMI, using amino acids analyser. Total amino acids, essential amino acids, non-essential amino acids and semi-essential amino acids were similar in T2D compared to healthy controls. Plasma concentrations of four essential amino acids were increased in the presence of T2D (Leucine, p &lt; 0.01, Lysine, p &lt; 0.001, Phenylalanine, p &lt; 0.01, Tryptophan, p &lt; 0.05). On the other hand, in relation to non-essential amino acids, Alanine and Serine were reduced in T2D (p &lt; 0.01, p &lt; 0.001, respectively), whereas Aspartate and Glutamate were increased in T2D compared to healthy controls (p &lt; 0.001, p &lt; 0.01, respectively). A semi-essential amino acid, Cystine, was also increased in T2D compared to healthy controls (p &lt; 0.01). Citrulline, a metabolic indicator amino acid, demonstrated lower plasma concentration in T2D compared to healthy controls (p &lt; 0.01). These amino acids were also correlated with fasting blood glucose and HbA1c (p &lt; 0.05). Glutamate, glycine and arginine were correlated with the duration of metformin treatment (p &lt; 0.05). No amino acid was correlated with lipid profiles. Disturbances in the metabolism of these amino acids are closely implicated in the pathogenesis of T2D and associated cardiovascular disease. Therefore, these perturbed amino acids could be explored as therapeutic targets to improve T2D management and prevent associated cardiovascular complications.
